Seriously, fans have adjustable speeds and are reversible so you don't blow directly on occupants.

Generally speaking, you can feel 75-100 FPM on your skin and you are going to start blowing papers around.
Get with a ceiling fan manufacturer, they can help you select an appropriate fan for your application. If the ceiling is sufficiently high and you want to use a single fan, Big Ass Fans specializes in this type of fan.
I also recommend googling "ceiling fan air flow patterns". Study the pictures and read through the white pages it brings up.

They HAVE cfm and room sizes listed! (Hint: Big room, public room = ONLY remote fan controllers or wall-side controller/veriable speed switches, NOT hanging chain pulls!)

It sounds like you have and know your requirements for the fans. Now you need to do some leg work, talk with some sales reps, and search manufacturer's engineering data in catalogues and online to find a fan that meets your requirements.
PS) That is your job.
